Evaluation of risk factors and effect of physical activity in caesarean section in nulliparous women

Abstract

Objective: The aim of this study was to evaluate risk factors for caesarean section (CS) in nulliparous women and to determine the effect of physical activity on ease of labour. Methods: A prospective observational study, including 282 nulliparous women at 37–41 gestational weeks was conducted. Maternal demographic characteristics, obstetric history and Modified Grimby scale for evaluation of physical activity were noted. Patients were classified into spontaneous labour and induction group. Multiple logistic regression model was used to assess independent risk factors for type of delivery. Results: Caesarean rate was increasing with higher educational status (p < 0.001). Maternal height, maternal and paternal age were higher, whereas dilatation on admission was lower in CS group (p < 0.05). Maternal age, weight gain and CS rate were higher in induction group (p < 0.05). Fetal distress as a cause of CS was detected higher in induction group (p < 0.05). Physical activity has no significant effect on mode of delivery (p > 0.05). Maternal height (p = 0.011), and cervical dilatation on admission (p = 0.004) were identified as predictor factors for CS. Conclusion: Cervical dilatation is the most important negative predictive factor for CS, whereas, moderate physical activity has no effect on mode of delivery. Fetal distress was the most frequent cause of CS in induction group.
